Patented Jan. 5, 1932 UNITED STATES JOHN A. KIMBALL, F TAYLORVILLE, ILLINOIS DOORKNOB MOUNT Application filed January 6, 1931.

This invention relates to door knob mounts and has for its primary object the provision of means whereby the knob may be mounted laterally, or to one side of the axial center of the operating rod of the lock or latch, whereby a downward or upward rocking movement of the knob will operate the door lock or latch so that the same may be operated by pressure of the arm, leg or other portion of the body, to enable a person to open the door whose hands are otherwise occupied.

Another object of the invention is to so mount the knob that it will be positioned close to the door and will thus not be liable to catch in the clothing of persons passing through the doorway.

Another object of the invention is the provision of a door knob mount which may be applied to a door lock or latch irrespective of the length of the operating spindle.

Another object of the invention is the provision of a door knob mount which will permit of circumferential adjustment of the knob to any position around the operating rod, so that the knob may be arranged in the most convenient position for use, or the mount may be used as a handle without the knob.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a fragmentary view looking at the edge of a door with the invention applied.

Figure 2 is a sectional view taken substantially on the line 22 of Figure 1.

Figure 3 is a longitudinal sectional view of the mount per se.

Figure 4 is an edge view showing a modified form of the invention.

Figure 5 is a face view of the same with the knob removed.

Figure 6 is a detail elevation of the sleeve shown in Figure 4, applied to one end of the operating rod of the lock.

Figure 7 is an edge view illustrating the use of the mount as a latch handle.

Serial No. 506,939.

Referring to the drawings in detail wherein like characters of referenc denote corresponding parts, the reference character 10 indicates the operating rod of a door latch or look, a portion of which is indicated at 11 and shown applied to a door 12.

The rod 10 is of the type commonly used in operating the latch bolts of mortise locks and is provided with a plurality of openings 13 for the reception of screws 14 whereby the knob 15 may be adjustably mounted upon the rod.

In the use of the present invention, the knob is removed from the rod 10 and adjustably mounted upon this rod is a sleeve 16 which is open at each end as shown in F igure 3 of the drawings. This sleeve is provided with a bore to receive the rod 10 and is adjustably positioned upon this rod by mca us of a screw 17 which is similar to the screw l4. By having the sleeve open at each end, it may be properly positioned upon the rod 10 adjacent the door 12 irrespective of the length of the rod.

Extending radially from the sleeve 16 is an arm 18 and this arm is offset as shown at 19. Extending from the outer end of the arm 18 is a post 20 which is cross section ally similar to the rod 10 and like this rod is provided with spaced openings 21. The knob 15 is adapted to be mounted upon this post and properly adjusted theron and held in adjusted position by means of the screw 14 which enters one of the openings 21.

By reference to Figures 1 and 2 of the drawings it will be seen that the knob 15 is radially offset with respect to the axial center of the rod 10 so as to provide a leverage whereby the door latch may be operated by moving the knob circumferentially about the rod so that the latch may be operated without requiring the use of the hands of a person for that purpose.

It will be further seen that by offsetting the arm 18 as shown, the knob occupies substantially the same position with respect to the door as it did if it were mounted directly upon the rod 10. In other words, the knob does not unduly project beyond the face of :spindle, a sleeve and having a serrated substantially circular the door so as to catch in the clothing of persons passing through the doorway.

In Figures t to 6 of the drawings, the rod 10 has mounted thereon a sleeve 22. This sleeve is provided with a reduced threaded portion 23 and a flange 24, one face of which is roughened or serrated. The arm 25, which is ofiset as shown at 26, is provided with an opening 27 for the reception of the threaded portion 23 of the sleeve, about which the arm may be freely rotated. A binding nut 28 is mounted upon the threaded portion 23 of the sleeve and acts to force the arm 25 against the serrated face of the flange 24 and securely hold the arm 25 against rotary movement upon the sleeve. adjusted in any position circumferentially of the rod 10, The knob 15 is mounted upon a post 29 which is removably secured to the arm 25 by means of a nut 30.

If desired, the arm may be mounted upon the sleeve as shown in Figure f the drawings. In this figure the position of the arm isreversed so that it will be spaced an appreciable distance from the adjacent face of the door 12 The post 29 is removed and the arm used as an operating handle.

The invention issusceptible of various changes in its form, proportions and minor 7 details of construction and the right is herein reserved to make such changes as properly fall Within the scope of the appended claim. Having describedthe invention what is claimed is bp The combination of a rotatable door latch detachably fitted thereon flange intermediate-thereof, a reversible distorted arm having one end adjustably engaged upon the sleeve to abut the flange, means removably locking the arm upon the sleeve and carried by thelatter, and a hand 'knob fastened at the free end of the arm on i the outer side thereof.
